Question

i have some queries which group datasets and count them, e.g.

  SELECT COUNT(*)
    FROM `table`
GROUP BY `column`

now i have the number of rows for which column is the same, so far so good.

problem is: how do i get the aggregate (min/max/avg/sum) values for those “grouped” counts. using a subquery sure is the easiest, but i was wondering if this is possible within this single query

Answer 1

For min and max you can ORDER BY and fetch the first row. For sum/avg/other aggregates you would need a subquery.
